~ 3.6-/ REPORT To the Honorabl~ Mayor and .City Council From the Ci Mana er May 23, 2005 Subject Final Acceptance - Redwood Shores Parkway Loop Detection Installation Project Recommendation Accept the Redwood Shores Parkway Loop Detection Installation Project, and authorize the release of bonds to S.G. Barber Construction, Inc. Background The previously existing traffic signal video detection systems located at: 1. Redwood Shores ParkwayfTwin Dolphin Drive, 2. Redwood Shores ParkwayÆlectronic Arts Drive/Market Place, and 3. Redwood Shores Parkway/Shoreline Drive/Hastings Shore Lane, have each been replaced with an in-pavement loop detection system. The video detection systems were replaced because they were found to be unreliable in detecting the presence of vehides under certain weather and lighting conditions. To compensate for this, some phases had to be programmed to provide a "fixed" green time during every cycle (whether or not vehides were present). As a result, the signal systems were operating less efficiently than desired, and causing additional unnecessary delay. The traffic signal's detection system, (whether it be video detection or in-pavement loops), is independent of the synchronization of the system, and therefore, replacing the detection system does not enhance the synchronization of the signals. However, there is a separate unrelated project currently underway, which is being performed by a consultant under a Traffic Engineering Technical Assistance Program (TET AP) grant, to review signal operations and develop updated signal coordination plans on Redwood Shores Parkway. This project ¡ndudes all four traffic signals on Redwood Shores Parkway between Shoreway Road and Shoreline Drive, and should be implemented by fall of this year. The City solicited for Informal Bid Proposals to perform the subject work. Three bids were received, with the lowest bid being from S.G. Barber Construction, Inc. of Belmont, California, for the amount of $88,300. The project has been successfully completed in accordance with the Plans and Specifications for a total cost of $88,300. No change orders were issued.
